Private, in-browser text and code diff checker with word-level highlighting
Read changes in two columns side by side, or switch to a single-column unified diff in the same format as git diff and patch files.
Darker highlights mark the exact words and characters that changed inside a modified line, not just the lines that differ.
The comparison runs entirely in your browser, so confidential code, contracts and config files never leave your device.
Ignore whitespace, indentation and capitalisation differences, and control how much unchanged context is shown around each change.
AI flashcards that turn note dumps and PDFs into addictive quiz sessions
Turn notes, PDFs, PowerPoint slides and YouTube videos into ready-to-quiz flashcards without writing cards by hand.
Automatic scheduling resurfaces cards right before you would forget them, so review time goes where it is needed.
Answer-first quizzing with instant feedback instead of passive re-reading, reinforcing long-term retention.
Streaks, points and social study sessions keep motivation high and make daily review a habit.
